ssiv A cord is a volume of cut wood equal to a stack \(8 \mathrm{ft}\) long, \(4 \mathrm{ft}\) wide, and \(4 \mathrm{ft}\) high. How many cords are in \(1.0 \mathrm{~m}^{3}\) ?

Short Answer

Expert verified
There are approximately 0.275 cords in 1 cubic meter.

Step by step solution

01

Understand the Volume of a Cord

A cord is a stack of wood with the dimensions: 8 feet long, 4 feet wide, and 4 feet high. To find its volume, you multiply these dimensions: \[8 \text{ ft} \times 4 \text{ ft} \times 4 \text{ ft} = 128 \text{ ft}^3\]So, the volume of a cord is 128 cubic feet.
02

Convert Cubic Feet to Cubic Meters

We have the volume of one cord in cubic feet. Now, we need to convert this volume to cubic meters since the problem asks for cords in \(1.0 \, \text{m}^3\). Using the conversion:\[1 \text{ ft} = 0.3048 \text{ m}\]The volume in cubic meters is:\[128 \text{ ft}^3 \times (0.3048 \text{ m/ft})^3 = 128 \times 0.028317 \text{ m}^3\]The conversion factor \((0.3048)^3\) is approximately 0.028317. Thus,\[128 \times 0.028317 = 3.624576 \text{ m}^3\]
03

Calculate Number of Cords in 1 Cubic Meter

Now, to find how many cords are in \(1.0 \, \text{m}^3\), divide 1 cubic meter by the volume of a cord in cubic meters:\[\frac{1.0 \text{ m}^3}{3.624576 \text{ m}^3} = 0.275128\]This means there are approximately 0.275 cords in \(1.0 \, \text{m}^3\).

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Cubic Feet to Cubic Meters
When converting cubic feet to cubic meters, it's important to understand the relationship between these two units of measurement. Cubic feet and cubic meters are both units used to measure volume, but they belong to different measurement systems. Cubic feet is part of the imperial system, commonly used in the United States, while cubic meters is a metric unit used globally.

To perform the conversion, you need to use a conversion factor that bridges these two systems. The fundamental conversion you need to remember is that one foot equals 0.3048 meters. To convert cubic feet to cubic meters, you cube this conversion factor. Thus, \[(0.3048)^3 = 0.028317 \]This means that one cubic foot equals approximately 0.028317 cubic meters.

Using this conversion factor, you can easily transform a given volume in cubic feet into cubic meters by multiplying by 0.028317.
Unit Conversion
Unit conversion is an essential skill in mathematics and science, allowing you to switch between different units of measurement. This process ensures that quantities are accurately and consistently expressed across various calculation contexts.

For volume, commonly converted units include cubic feet (ft³) to cubic meters (m³). The conversion process requires applying a conversion factor. This factor is derived by understanding how base units relate to one another.

For example:
  • Calculate the equivalent value in another unit by multiplying the original measurement by the conversion factor.
  • Ensure the units cancel out accordingly, leaving you with the desired unit as the remainder.
Mastering unit conversion enables you to tackle problems involving different systems of measurement smoothly and efficiently.
Volume Measurement
Volume measurement is the process of determining the amount of space an object occupies. This quantification can vary depending on the unit of measurement used. Both cubic feet and cubic meters are standard units for measuring volume.

The choice of unit often depends on the conventional system used in particular contexts or regions:
  • Imperial measurements, such as cubic feet, are commonly used in countries like the United States.
  • The metric system, using cubic meters, is more prevalent in most parts of the world.
Volume is typically calculated by multiplying length, width, and height for rectangular prisms. For example, a cord of wood is traditionally measured in cubic feet, calculated by the dimensions of 8 feet by 4 feet by 4 feet, leading to:\[8 imes 4 imes 4 = 128 ext{ ft}^3 \]These fundamental skills are crucial in various practical applications, from engineering to everyday logistics.
Dimensional Analysis
Dimensional analysis is a method used to convert one type of unit to another, using the relationships between units. It involves multiplying the original measurement by one or more conversion factors that cancel out the unwanted units and introduce the desired units.

For instance, when converting cubic feet to cubic meters:
  • Start with your known volume in cubic feet (e.g., 128 ft³).
  • Use the conversion factor \[(0.3048 ext{ m/ft})^3\] which represents converting individual feet to meters and then cubing the dimensions to convert volume.
  • This systematic technique ensures you multiply by the proper factors, maintaining dimensional accuracy.
Dimensional analysis not only simplifies complex conversion problems but also reduces errors, enhancing precision and confidence in mathematical calculations.
